Sonoma, Painting Speaker Grill

I have a 99 Gmc Sonoma Ls Series, I Want to Paint the Speaker Grills (One on doors and top of dashboard) Blue, Heres my Issues, Door Grill is Fine, But the ones on the dashboard have Extremly Small Holes and if i Paid them with a Rattle can or buy a paint gun for my compresser i'm affarid of cloging all the small holes, i was told to put a toothpick in them but OMG theres over 300 in one! I am a Novice At This so Simple Ideas lol and Should i Clear Coat them?

I would think that leaving it on and painting would be problematic. You'll just have to put something like a toothpick in there, which isn't that big of a deal, you're in maybe 5 minutes of work to prep with that.

no update as of yet, ran into a snag with cash but back at it, did the girlfriends car yesterday, Hot Pink lmao but on mine i can take the Trim of it off but i am not sure how i can paint the actual dashboard without taking it 100% Completly out of the car i want to avoid the electrical plugs etc, any tips idea's? is the Plastic behind held onto the Dashboard Housing with Clips or is it 100% One Peice?
